This is a no-changes port of the Fraunhofer Institute MPEG audio decoder,
Version 4.1. It supports compression layers 1-3.

The MPEG-audio compression standard provides exceptional compression
ratios for audio samples of 32 KHz (DAT-LP), 44.1 KHz (CD) and 48 KHz
(DAT-SP). The only disadvantage of MPEG-compression is the sloooow
speed. This decoder takes 1:28 minutes on a A4000/040/28(WARP) to
decompress the included example which is a 15-second mono sample in
CD-Quality (44.1 KHz).

Included is the full sourcecode, three executables (68000/FFP, 68020/IEEE
and 68040/internal FPU) and an example file compressed using layer 2
compression.

Suggested way for playing MPEG-samples on the amiga:

Decoding using this program:

- Start decode0x0
- Type the name of the compressed sample (eg. foobar.mp2)
- Type the name for the decompressed sample (foobar.sw)
- Type "n" twice

Converting using AmiSOX:

- Type "sox -r 44100 foobar.sw foobar.wav"

Playing using Play16:

- Type "play16 foobar.wav fast hifi"

This way, you can listen to the samples in 14-bit-quality, which you cant if
you convert to 8SVX.

many freely distributable pieces of high quality music. The example file
is also from there.
